My 4 year old is the same and he also has a very stubborn personality, is very sensitive, intensely smart and inquisitive- all in all - a perfect storm for continuous questioning boundaries, sass, testing the limits, being contentious and melting down over seemingly small things. It’s definitely tough at the moment, but I’m hoping when they start to emotionally regulate a bit better things will calm down a bit. Just be assured that it’s developmentally appropriate and normal at that age for them to be challenging everything. X
I think it’s the age. My daughter’s the same. Gets far too overly excited around her brothers (4m twins) and the attitude! My lord it’s like having a teenager! However my friends kids are the same so I’m reassured it’s normal
